Here's the thing, often people who are against abortion also whine and moan about those same kids being on welfare most of their lives, they also complain about the kids being raised wrong and in bad environments. If they truly cared about the children they would need some solution, the only three that would make an impact are abortion, forced adoption, or forced sterilization. Otherwise you can't whine about the kids on welfare because you don't are not allowing for any solution to the problem. That is why it would be. Oh, and to be clear, not saying you in particular it's a broad statement.
I actually agree with you on the whining part by conservatives.
For me, I'm not totally anti-welfare, but I would like it to incorporate some MANDATORY elements: mandatory education, mandatory job skills training, mandatory classes in nutrition, budgeting, and other life skills.
People make mistakes, and I totally understand that. But if we REALLY cared about poor people, we would give them the skills they need to escape from poverty, rather than keeping them trapped in dependency on the government.
I've known too many poor people who raised exceptional kids to say that we should force them to be sterilized or give up their children simply because they are poor.
